The Contraindications Clients Don’t Mention: Epilepsy, Pacemakers, Antibiotics & Breastfeeding

This is the third guide in our contraindication series. The medication guide covered prescriptions like Roaccutane and retinoids; the skin conditions guide covered what walks in visibly on the skin. This one covers the contraindications with no visual tell at all: epilepsy, cardiac implants, a short course of antibiotics, and breastfeeding. Clients don’t hide them — they simply don’t connect a facial with their heart, or a laser slot with last week’s prescription.

Whether you’re a solo therapist in Peckham or a five-room clinic off Harley Street, the standard is the same: ask, record, and make the answer impossible to miss at the next booking. None of this is medical or legal advice; your insurer and each device manufacturer set the definitive rules for your services.

1. Can I treat a client with epilepsy in my salon?

Usually yes — but some treatments need adjusting or a GP’s go-ahead first, and it depends on how well controlled their epilepsy is. Epilepsy isn’t a blanket contraindication; treating it as one is both unfair to the client and bad practice.

• Light-based treatments. LED therapy, IPL, and laser involve intense or flickering light. For photosensitive epilepsy — a minority of cases, but you won’t know unless you ask — these can trigger a seizure. Get written GP or specialist consent before any light-based treatment.
• Electrical treatments. Microcurrent, radiofrequency, faradic, and galvanic work are generally contraindicated without medical clearance — most insurers expect it in writing.
• Massage and heat. Deep relaxation and heat (steam, hot stones) can occasionally lower the seizure threshold in poorly controlled epilepsy. Fine for most clients — but ask when their last seizure was and whether their medication is stable.
• Plan for the “what if.” Know where the client would be safest if a seizure happened mid-treatment — never mid-wax with hot product open, never unattended with their head over a backwash.

Ask at consultation, record the answer, and record the GP consent if you needed one. The risk isn’t the treatment — it’s not knowing, or knowing once and forgetting by their next visit.

2. Can I use microcurrent or radiofrequency on a client with a pacemaker?

No — for microcurrent, it’s an absolute contraindication. Microcurrent facials, EMS body toning, and galvanic treatments pass electrical current through the body, and that current can interfere with a pacemaker or implanted defibrillator (ICD). No UK insurer will cover you for running current through a client with a cardiac implant, and no reputable device manufacturer sanctions it.

Radiofrequency is nearly as strict: RF skin tightening generates an electromagnetic field, and most manufacturers list pacemakers and ICDs as a contraindication for exactly that reason. Some clinics will treat a limb far from the chest with written cardiologist clearance — but for a solo salon or spa, the safe and insurable answer is don’t.

• Ask about cardiac implants on every consultation form — pacemaker, ICD, loop recorder. Clients rarely volunteer it because they don’t connect a facial with their heart.
• Offer the alternative in the same breath. Manual facials, most massage, LED therapy, lashes, brows, waxing, nails and most skincare are all still on the table. A pacemaker rules out the current, not the client.
• Never accept “it’s fine, I’ve had it done before.” Previous luck is not clearance.

3. Can I do laser or IPL on a client taking antibiotics?

Not while they’re on a photosensitising antibiotic — and many common ones are. The biggest offenders are the tetracyclines, doxycycline and lymecycline, both routinely prescribed for acne — so they turn up constantly in laser hair removal clients. Ciprofloxacin and trimethoprim can also photosensitise. Treating over them risks burns, blistering, and post-inflammatory hyperpigmentation — exactly the injuries that generate complaints and insurance claims.

• Ask about medication at every appointment, not just the first consultation. Antibiotic courses are short and clients rarely think to mention them.
• Mid-course? Rebook. Standard guidance is to wait 1–2 weeks after the final dose — some device protocols say longer for tetracyclines, so check yours.
• Long-term acne prescriptions (ongoing lymecycline or doxycycline) need a conversation with the prescriber before you treat. Don’t work around an active prescription.
• Patch test after any medication change — non-negotiable, and your insurance almost certainly requires the medication check before every light-based treatment.

Record the medication, the decision, and the rebook date. If a reaction ever occurs, your notes are your defence.

4. Which salon treatments need caution for a breastfeeding client?

Breastfeeding is the contraindication salons forget to ask about. Pregnancy is on every consultation form; “are you currently breastfeeding?” often isn’t — and several treatments that were paused during pregnancy stay restricted after the birth.

• Injectables and advanced aesthetics: Botox and fillers are almost universally declined for breastfeeding clients — most practitioners’ insurance simply won’t cover it.
• Chemical peels and strong actives: high-strength acids and anything containing retinoids stay off the table. Topical retinoids are contraindicated while breastfeeding, and peels aren’t tested for it.
• Laser and IPL: many providers treat breastfeeding as a caution rather than a hard stop — but avoid the chest and breast area entirely, and check your insurer’s exact wording. Some require GP sign-off.
• Aromatherapy and essential oils: several oils are flagged for breastfeeding, not just pregnancy. A “post-natal safe” blend needs checking oil by oil.

Generally fine: hair services, nails, standard facials, waxing, and massage — with comfort positioning and the usual sensitivity awareness, since post-natal skin can still be reactive. The operational trap: a client who told you she was pregnant in February walks back in come summer, and nobody asks the follow-up question. If the answer isn’t on a dated record, you’re relying on memory.

5. What should a salon consultation form ask — and how do you keep the answers current?

Every contraindication on this page fails at the same point: the form. A paper consultation card asks once, gets filed, and is out of date by the client’s next visit — the antibiotic course started after it was signed, the pregnancy became breastfeeding, the pacemaker was fitted last winter. If you’re comparing salon consultation form software in London or anywhere else in the UK, the test is simple: does yesterday’s answer surface at tomorrow’s booking, unprompted?

Three questions belong on every form and every rebooking check: any medical conditions or implants (epilepsy, cardiac devices, diabetes), any medication changes since last visit, and pregnant or breastfeeding. Each answer is health data — special category under UK GDPR Article 9 — so it needs a proper record with restricted access and a retention limit, not a notebook or a group chat. That’s the gap SAY-OS closes: a structured per-client safety record, held to the Article 9 standard, that flags the contraindication the moment the risky treatment is booked — the app that remembers everything for you, so the safety call happens before the client is ever in the chair.
